In firmware version 1.20 we have changed the way how call routing is set up. This FAQ is going to show you how to set 2N® VoiceBlue MAX in firmware 1.20+.

If you are currently using firmware that is older than version 1.20 (1.19 and lower) please upgrade your firmware version or go here: older FW version, where you will find FAQ on how to set 2N® VoiceBlue MAX in older FW version.

 

SIM Card Placement

Insert the SIM cards into one of the four SIM holders on the 2N® VoiceBlue MAX front and make sure that the chip contacts are at the front bottom. The SIM holders are equipped with the push&pull technology for facilitation.

How to connect to the 2N® VoiceBlue MAX


How to set up the Call Routing

In the VoiceBlue MAX calls can come from the FXS Ports or from the VoIP port and calls are routed to any GSM/UMTS port according to the LCR (Least Cost Routing) table. If the GSM port is busy, other ports are checked automatically for availability (depending on the configuration) and in case if an allowed outgoing port is not available, the outgoing call will be rejected.

The LCR algorithm identifies the outgoing call type, current time tariff rate, day in a week, eventually free minutes of GSM providers and routes outgoing calls accordingly. Incoming calls from GSM networks are routed directly either to the FXS Ports or to the defined SIP address, or the DISA function is activated. Furthermore, calls can be routed according to the CLIP (caller's telephone number). And the CallBack service is also available.

If you want to check current settings of call routes, go to the Menu Gateway Configuration / LCR table

How to set up the LCR Table

The LCR (Least Cost Routing) helps you select outgoing call routes according to the port the outgoing calls is originating from (FXS, GSM oe VoIP), called subscriber's number (or some prefix), time of the day and weekdays. 

Whenever a call is being done, the LCR table is searched sequentially from top to bottom. If the called destination prefix matches the network prefix included in the List of networks table (and designated as Network number in the LCR table), the call is routed according to the routing group parameters (Groups in the LCR table) as set in the GSM outgoing groups table. The call will be connected via the GSM module which was assigned to the GSM outgoing group in the Assignment to GSM groups table. 

Therefore, you need to set and configure:

 Example 

  Let’s say we have SIM cards of two GSM operators:

Configuration of GSM outgoing groups

You are able to set up different settings for each GSM group (CLIR, free minutes, Virtual ring tone, roaming and others).

  1. Prefix lists

    We have to create two network lists, the first one for both of the Operators.

      1. Operator 1 network list:
        We configure the normalization of Called party number in the Table of replaced prefixes (the number in front of the slash mark is replaced by number behind the slash mark, if there is not any number in front of the slash mark it equals to “everything”).
        We also have to fill in the Table of prefixes with all prefixes of the Operator 1. Because all numbers are 9 digits length, it is not necessary to specify each prefix, we can use the parameter Default count of digits and fill there the value 9.
        The Table of replaced prefixes, Table of accepted prefixes and Digits count must correspond with the called number and it leads to the match in prefix list
      2. Operator 2 network list:
        We configure the normalization of Called party number in the Table of replaced prefixes (the number in front of the slash mark is replaced by number behind the slash mark, if there is not any number in front of the slash mark it equals to “everything”). We also have to fill in the Table of prefixes with all prefixes of the operator 2. Because all numbers are 9 digits length, it is not necessary to specify each prefix, we can use the parameter Default count of digits and fill there the value 9.

LCR Table
We have to configure rows in the LCR table where we bind together GSM Outgoing groups with Prefix lists and ports where call is originating.

Please note that LCR table is searched sequentially from top to bottom. So position of each rule in LCR table is important. If there is a match found in a LCR rule than the call is routed to the destination specified in that rule. All other rules that are after the succesfull one do not matter.

 In default LCR table looks like this:

Where each line means following:

To complete setting of our scenario we need to add 2 more lines (or only 1 based on if you are calling only from FXS or only from VoIP). We already have 2 lines that are routing outgong calls from FXS ports to GSM outgoing group 1 and calls from VoIP to GSM outgoing group 1. We need to add only lines for outgoing GSM groups 2.

  1. Add rule for calls from FXS to GSM outgoing group 2 (called number must match Prefixlist 2)
    Click on ADD button to add new line and configure it for Operator 2
    Click on OK and move the LCR rule into position under 2nd line.
  2. Add rule for calls from VoIP to GSM outgoing group 2 (called number must match Prefixlist 2)
    Click on ADD button and add new line and configure it for Operator 2 
    Click on OK and move the LCR rule into position before the last line 


Now your LCR table should look like this:
